Taylor Swift is so smitten with Conor Kennedy that, after leaving him in Massachusetts to head back to Nashville, she missed him so desperately she sent a jet to pick him up from the Kennedy home.

Sources exclusively tell Page Six that country superstar Swift left the Kennedy family compound in Hyannis Port alone just over a week ago to go to Nashville to work and promote her new single, “We Are Never Ever Getting Back Together.”

But one source said, “Taylor missed Conor so much, she sent a plane for him a few days later. He’s been with her ever since, and his family doesn’t know when he will be back. Things have become so serious between them so fast that no one in Hyannis Port would be surprised if they eloped.”

A Kennedy source told us that despite their still-brief romance, which they say started in July, Swift seems “totally in love with Conor. They are inseparable and are all over each other all the time. While his relatives really like Taylor, some feel their lovey-dovey behavior is cute while it has made others in the family feel a little uncomfortable.”

The love-struck pair crashed the wedding of Kyle Kennedy in Boston. The bride’s mother, Victoria Gifford Kennedy, said she had asked them via text not to come, then asked Swift to leave twice. But, “It was like talking to a ghost. She seemed to look right past me.”

Another source close to Swift, 22, said, “She always falls very hard and becomes very intense very quickly, and this time is no exception. In fact she seems to have fallen even harder.”

According to reports, Swift even bought a home next to 19-year-old Conor’s family. And she was spotted holding tight to him while accompanying him and his siblings to their mother Mary Richardson Kennedy’s grave site.

Reps for Swift, who so far have not commented on the relationship, didn’t get back to us last night.
